Electrons can be shared unequally in a molecule, creating a polar molecule. Opposite polar ends of molecules attract and hold one molecule to another. Alcohol has one O–H bond which is polar, but a ...

Sucrose has many O–H bonds which are polar. These polar areas are shown with a + near the hydrogen atom and a − near the oxygen atom. The second space-filling model shows two sucrose molecules held ...

When a charged object such as a rubber balloon is brought close to a fine stream of a polar liquid, the stream is attracted toward the electrical charge. If the same charged object is brought close to ...
